You can buy PAL to NTSC convertors but for game machines this is a poor choice. I'd say to bite the bullet and get another Wii but add more advice and see if Nintendo rolls out a new HD Wii by Christmas.
I bought the Wii from London UK. Now I am in Canada.
I purchased a component cable for Wii to connect to HDTV. But when I connected, I am not getting any picture instead I am getting resolution is not supported by TV.
Please let me know how to solve the issue.
